If the mags work in the DPMS? The innards of the PSA lower, is out of spec. Coat the external surfaces of the mag, which is the best fit. With something like Prussian Blue or lipstick. To see where it's binding in the mag well. Depending where it's binding, you might need something like a die sinkers file. To clean up the internal surfaces of the mag well.

Considering the current price of mags, just replace or mark which rifle they work in.

Have you adjusted the mag catch?

Assuming the mags work fine in one of your rifles, I wouldn't alter them. If you have the same issue with multiple mags from different manfacturers, it almost certainly isn't the mags themselves. . .its the gun.

Are these hard to insert as well as remove?

Assuming the mags lock into place, don't wiggle, then release properly, the mag catch probably isn't the issue. Much more likely, the PSA lower mag well is slightly out of spec.

A very easy thing to do is just remove the mag catch and see if the mags still bind. Assuming so, you know it isn't the catch. (If they slide in and out no problem, then try replacing the mag catch. . .that's cheap and easy).

I think Rufe has it. Just put some marking ink (Sharpie ink could work) or paint on a mag, put it in and out, and see where the mag well rubs the mag. Once you figure out where the issue is, you might be able to fix it pretty simply by removing a small amount of metal from the magwell using a file.

I'd just do maybe 1-2 strokes, retry, 1-2 more, retry, etc. Chances are it won't take much to fix this. .

Use a new Military or other good manufacturer's mag to check for fit.
If it's good as I expect, measure the width at and below the feed lips.
Then measure your other mags to see where they're too fat.
Judicious pinching in a vise and remeasuring should correct mag fit.
During the big mag scare, I bought a bunch of well used Army mags and found some needed adjusting.
It's probably from keeping mags loaded too long.
If this isn't the issue and new high quality mags don't fit freely,
you need to cut metal but only if you are good with a file.
Otherwise let someone else do it.
It's best if you can copy dimensions from someone elses' lower
before removing metal.
